It has been suggested that List of Solar System objects most distant from the Sun in 2015 be merged into this article. (Discuss) Proposed since December 2018.
This is a listing of minor planets orbiting the Sun by their approximate distance from the Sun in March 2018 (as opposed to those with the greatest calculated aphelion in their orbit). In March 2018 several new Trans-Neptunian objects (TNOs) with a current heliocentric distance greater than 50 AU were announced by Scott S. Sheppard, Chad Trujillo, and David J. Tholen.
Trans-Neptunian objects are typically announced publicly months or years after their discovery, so as to make sure the orbit is correct before announcing it. Due to their greater distance from the Sun and slow movement across the sky, trans-Neptunian objects with observation arcs less than several years often have poorly constrained orbits. Particularly distant asteroids discovered in 2018 may only be announced in 2020 or later.
